ASI533-H00 S1 Analog Output Module | Yokogawa

Configured for 4-20 mA DC signal generation in Yokogawa DCS platforms, the Yokogawa ASI533-H00 S1 (ASI533 Analog Output Module) provides eight isolated analog output channels for direct field-loop control. Each channel supports up to 23 mA output and accepts defined load resistance limits. The module also supports HART communication when the system configuration enables this function.

Hardware Specifications

Yokogawa Analog Loop and Isolation Characteristics

The ASI533-H00 S1 generates 4-20 mA DC control signals for connected field devices. Therefore, each output channel can drive a defined analog control loop within the specified load resistance range.

Furthermore, the eight output channels use galvanic isolation. This arrangement electrically separates field-side circuits from the module's internal signal-processing circuits and limits direct electrical interaction between isolated sections.

The module supports HART communication when the associated Yokogawa system configuration provides the required communication path. However, the supplied specifications do not define a separate HART channel count or HART electrical loading limit.

The module updates output data every 10 ms and specifies a 100 ms step response time. These values define the module's data handling and output response characteristics for analog control applications.

Frequently Asked Questions

Q: How many analog output channels does the ASI533-H00 S1 provide?
A: The module provides 8 fully isolated analog output channels.

Q: What output range does the module support?
A: Each analog output operates within the 4-20 mA DC range, with a maximum output current of 23 mA.

Q: What load resistance can the output drive?
A: The specified load range is 0-750 ohm at 20 mA and 0-600 ohm at 23 mA.

Field Installation Guidelines

• Install the module according to the applicable Yokogawa system hardware documentation and approved rack configuration.
• Verify the module model and terminal assignment before connecting field wiring.
• Confirm that each connected loop remains within the specified load resistance range.
• Route analog signal wiring separately from high-voltage and high-current conductors where practical.
• Use appropriate cable shielding for analog signal circuits according to the site's grounding standard.
• Connect cable shields according to the Yokogawa system grounding design; avoid creating unintended ground loops.
• Verify output polarity before energizing connected field devices.
• Check the 5 VDC and 24 VDC power requirements against the installed system power distribution.
• Confirm isolation requirements before connecting external circuits to separate output channels.
• If HART communication is required, verify system configuration and field-device compatibility before commissioning.
• Perform an output-loop verification after installation by checking the commanded current against the connected field-device response.
